The Ray Allen Trim Servo unit use a gear drive from a small electric motor that locks where it's at when the voltage is removed. I suspect that Dan's Sable mirror motor is very similar. A RC servo has to have voltage to hold a position. The heavier the load against it, the more amps it needs to pull and the more likely it is to fail. If I found an RC servo in the trim on a Tech Counselor inspection, I would advise the builder to remove it. If I found it on a condition inspection, it would have to be removed before it gets a signature in the logs. The DAR was right on the money with his recommendation. Jeff Scott A&P
